| Abstract: | Electrochemical reduction of europium cryptatcs Eu(NO3)3(2,2) and Eu2(NO3)6(2,2,2) were investigated by means of cyclic voltametry in dichloro-methane, dichloroethane, acetonitrile, acetone, benzonitrile, pyridine, dimcthyl-formamidc and dimethyl sulioxide, The halfwave potentials of redox reaction and electron-transfer rate constants were determined, and the effects of solvent and supporting electrolyte on E1/2and kswere discussed. |
